It depends how you screwed it up so your opposite stopped talking to you so you wanna make them talk back to you again!
Broken trust
Broken promise
Disrespecting & insulting
Lying & lying about lying
Doing something that you knew it might hurt them
all these list above, when they happen, it's not easy to heal the pain you caused. So it depends how you really screwed it up. And in general, (Time) time will make things better automatically. So just give it time as well.
